SODA-WATER APPARATUS.

SPECIFICATION forming part 0f Letters Patent No. 582,248, dated May' 11,1897.

Application filed J'uly 16, 1896. Serial No. 599,385. (N0 model.)

To all whom t may concern:

Be it known that I, ELMER A. WiLcoX, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Soda Water Apparatus, of whichthe following is a specification.

This invention has for its object the provision of a practical, cheap,light, and durable construction of soda-water apparatus adapted to besecured to any counter or table or to be carried about and set uptemporarily. It is intended to be arranged above the counter or table;but the tank or vessel containing the soda solution is located under thecounter or table and out of sight, so that the apparatus, so far as itis presented to view, is pleasing in appearance and takes up but littleroom.

The invention relates to the details of construction whereby I amenabled to thus use the apparatus, and these details are fully set forthin the description which I give below.

In the drawings, Figure l is a perspective of the apparatus aspositioned for use upon the counter. Fig. 2 is a side elevation of theapparatus. Fig. 3 is an enlarged vertical section of the valve-chamberand of the adjacent portion of the pump-cylinder. Fig. 4 is a partialsection of the top of the pumpcylinder. Fig. 5 is an enlarged section ofone of the valves.

In said drawings, A represents a counter or table having my apparatuspositioned thereon.

B is a tank or vessel placed below the counter and containing a solutionof soda, and a pipe h extends from the pumping apparatus into this tank,so that the contents of the tank can be drawn upward and used in theformation of the beverage. Pipe b leads into a valve-chamber which ispreferably made in three parts or sections C C O2, shaped and unitedtogether by threaded joints, as shown at Fig. 3, the middle portionforming a coupling. whereby to unite the outer portions. The lowersection contains a branch iiuidpassage c, connecting with the bottom ofthe pump-cylinder D, while the section C2 of the casing receives thelower end of the dischargepipe E. In the valve-casing are two valves Fand G, each having an appropriate chamber, and suoli chambers areconnected by a passage g.

In theA main or pump cylinder is a piston D', havingarod erstem D2extending through the top D3 of the cylinder and also passing throughthe frame II, so as to be guided by such frame in its movements. Thepiston is provided with packing d, so that it forms a perfectly tightjoint with the interior surface of the cylinder and it is operated bythe handlever J which is of the peculiarform shownthat is to say, it isS-shaped. In making this lever of this shape I have several objects inview. One is to shape the handle so that it will be convenient tooperate in all its positions.' Anotheris that it may rest squarely uponthe top of the cylinder when depressed to its lowest position, and athird is to give it a pleasing appearance. It is joined to the pump-rodby a pivot-bolt J and has a swinging fulcruin obtained by joining it tothe upper end of a link J 2, pivoted to the projection J3 upon the frameI-I. In this manner I avoid the necessity of providing the lever withany attachment to the pump-rod which will shift in position, and thefulcrum and weight of the lever remain at a fixed distance apart. Thelever is forked at one end, as plainly shown, so it may pass upon bothsides of the frame II and the pump-rod.

rlhe frame II serves not only as a guide to the pump-rod, but it alsoserves other purposes. It is provided, for instance upon its innersurface, with studs K, which set down over the cover D3 and not onlyhold that cover in position, but through it they also hold the cylinderitself down. The sides of the frame are positioned a proper distanceapart to insure the cylinder D being accurately positioned when placedbetween them. The ends of the frame, which is U-shaped, as shown, alsoextend forwardly and are threaded so that by means of the nuts L thewhole of the apparatus may be readily and firmly attached to the counterand as readily detached therefrom. The valves F and G each consist of adisk f, having attached thereto 0r integral therewith buttons f',located at their centers, and they are provided with packing consistingof a rubber disk f2, having a central opening which may be sprung overthe button f',

IOO

thus securing the packing permanently to the valve. The valve-chambersare provided with depending pins g', intended to limit the upwardmovement of the valves and preventing their closing the upper orificesopening from their chambers.

The cover D3 has an offset around its edge, as shown at cl3, so thatwhen positioned upon the cylinder it cannot move in any direction exceptan upward one, and any movement in that direction will be prevented bythe lugs K.

It will be noticed that the apparatus is readily taken apart whenevernecessary for repairs or cleaning, and it is in order to obtain thisfacility that I make the valvecas ing in the manner shown.

The operation of the invention is as follows: Supposing the tank B to befilled with a soda solution and the syrup containing the acid and thealbumen to be placed in a drinkingglass and held under thedischarge-pipe, the hand-lever is raised from its lower position, (shownin the drawings,) thereby creating a suction which opens the valve F anddraws up a charge of the soda solution from the tank. This suction ofcourse also causes the closing of valve G, so that the soda solutionwill be drawn into the pump-cylinder. A downward movement is now giventhe handlever and causes a closing of valve F and a forcing of thecharge of soda and water upward through valve G and into and through thedischarge-pipe E into the glass containing the syrup and otheringredients and causing the customary effervescence in the glass. Thiseffervescence will be greater or less, according as the lever is moveddown quickly or slowly, the quick movement producing the greatereffervescence and the slow movement producing little or none, so that itwill be seen that the various tastes of customers can be catered tobythe machine without diliculty.

The invention is not only adapted to the production of an apetizingarticle of sodawater, but also in preparation of hot soda, beef-tea,milk-shake, and many other popular beverages.

I claim- 1. The combination with a soda-water pump of a U-shaped framehaving its lower ends threaded and of sufficient length to extendthrough the counter, so that the frame may be secured to a counter, andalso having lugs K whereby it may contne the pump-cylinder and lid,substantially as speciiied.

2. The combination with a soda-water pum p of an inverted- U frame Hsetting over the cylinder of the pump and serving as a means of securingit down upon the counter, and also as a support for the fulcrum of theoperatinglever, substantially as specified.

3. The combination with a soda-water pump, of a U-shaped frame H havinglugs K and projection J, with the cylinder arranged inside the frame andhaving a removable cover kept in position by said lugs, a leversupported by said projection, and means for attaching such frame to thecounter, substantially as specified.
